An Opacity-Free Test of the Cosmic Distance Duality Relation Using Strongly Lensed Gravitational Wave Signals with Space-Based Detector Networks

Yong Yuan, Minghui Du, Benyang Zhu +4

The cosmic distance duality relation (CDDR), expressed as $d_L(z)=(1+z{)}^2{D}_A(z)$, is a fundamental relation in modern cosmology. In this work, we apply a method to test the CDDR…
